ICE-CREAM CABINET.

Application tiled May 29, 1924. -Serial No. 716,666.

lVith these ends in view the invention re' sides essentially in the provision of a protec- `tive collar adapted to surround and snugly lit the upper end of the refrigerated product container or can of the cabinet, in conjunctionwith an annular cove,- adapted to lit within the upper endrof the refrigerant container, or tub of said cabinet, and to fit within the upper end of said collar, to thus Compleat-ly enclose the refrigerant contained in the annular chamber formed between 'sa u can and said tub, while effectively and positively preventing the said refrigerant from entering said can and destroying the purity ot" the contents thereof.

The invent-ion lfurther resides in the provision of an ice cream cabinet requiring the minimum attention to and repacking of the refrigerant medium thereof, whereby the use of such refrigerant medium and the time and energy .of the operator is economized and conserved.

The invention further resides'in vthe provision of an ice cream cabinet, that is simple and durable in construction, etlicient, reliable and sanitary in use and that may be manufactured at a comparatively low cost.

The invention further resides in the novel construction, combination, adaptation and arrangement of parts. as will hereinafter be more fully described and succinctly defined in the appended claims.

Referring now to the accompanyinef draw-- ings wherein is illustrated the specitic form of the invention, as at present preferred:

Figure l is a top plan view of an ice cream cabinet fabricated in accordance with the invent-ion, having certain parts thereof broken away or omitted for clearness of illustration.

Figure .2 is a vertical transverse section taken through 2-2 of Figure l, and,

Figure is an enlarged fragn'ientary view iii-medial vertical section ot the upper por-- tion of the cabinet.

In the accompanying drawings and in the following description l. have elected to illustrate, and describe the invention as embodied 4in a single compartment cabinet, but, mani- IJfcstly the iinprovements may be embmlied in cabinets having` two or more compartments without departing from the spirit of the invention or the benefits derivable therefrom, the present showing being merely by way of illustration.

Referring now to the accompanying drawings wherein like reference characters designate like parts throughout the Several views, the numeral 5 designates an outer alsiiig of the ice cream cabinet having a cylindrical inner casing or tub 6 rigidly secured and symmetrically disposed therein, in spaced re- I lation therefrom and havlng an insulating'l material or filler 7, such as granulated cork, interposed therebetween, substantially as shown in Fig. 2. The casing or tub 6 is provided contiguous to the lower end with a drain conduitS havinga stop cock 9 disposed upon the outer end thereof, whereby the accumulated liquid in the tub 6 may be readily drawn ott' when desired.

Concentrically disposed withinithe tub 6 isa perforated cylindrical ice drum l() having feet 11 rigidly secured thereto upon the lower end thereofadapted to rest upon the bottoni wall of said tub. The external diameter of the ice drum l-O is substantially reduced relative to the internal diameter of the tub 6, to provide an annular space therebetween for crushed ice or other suitable refrigerant 12, while the height of the ice drain 10 is also .substantially reduced relative to the height of the tub 6, to thereby dispose the upper end of the said ice drum in a lane below the planeof the upper end of said tub, substantially in the manner and relative planes illustrated in Figures 2 and 3.

Concentrically disposed within the ice drum l() is an ice cream can or container 13 adapted to rest upon the bottom wall of the tub 6 and having an integral external bead 14 formed thereon adjacent the upper end thereof. The external diameter of the can 13 is slightly less than the internal diameter of the perforated ice drum 10, to thereby provide an annular space therebetween, while the height of said can is slightly less than the height of the said drum, as shown in Figures 2 and 3.

Interposed between the upper endsoi the ice drum lO'and can 13 and extending upwardly therefrom is a cylindrical protective collar 15 having a gasket 16 seated within an annular groove 1T formed upon the lower end thereof. The gasket 1G is adapted to normally abut and restrainingly engage the external bead 1-1 formed upon the can 13, to thereby retain the collar 15 in position thereon, and when thus positioned the collar 15 prevents the refrigerant 12 from entering the'vcan 13, thus preserving the contents'thereof in a clean and wholesome condition, as will be readily apparent.

Seated within and abutting the upper end of the tub 6 is an annular cover or closure 18 having a downwardly extending and concentrically disposed cylindrical extension or thimble 19 rigidly secured therein, adapted at the lower end thereof to project and tit snugly within the protective collar 15, to thereby completely enclose and protect the refrigerant 12 against the deteriorating action and effect of the surrounding air, while also positively preventing such refrigerant from entering the ice cream can 13.

The ice cream can 13 is provided with a cover 20, of any well known type, having a hand hold 21 rigidly secured thereto. The cover 2O is adapted to normally seat upon the gasket 16, as shown, to thereby positively cut off the contents of the can 13, from the surrounding air, as will be readily understood.

A cover 22 is adapt-ed to seat within and abut the upper end of the annular cover 18, whereby the ice cream cabinet is completely closed and the contents thereof fully protected.

Manifestly with the several elements con- 4stituting the ice cream cabinet disposed in the relative positions illustrated in Figure 3 clear and unobstructed access is had to the contents of the ice cream can 13 while the refrigerant 12 is fully preserved and protected from the surrounding air and is efectually prevented from entering said can 13, thus insuring and assuring of the contents of the can 13 remaining in a wholesome andsaleable condition. The double covers 20 and 22 also aid in preserving the contents of the can 13 in the condition above described.

'By enclosing the refri in the manner shown an erant medium 12 described, it will be obvious that the ice cream cabinet herein disclosed embodies the maximum in sanitation, further, the necessity of constantly repacking the refrigerant, as obtains in the ice cream cabinets now in use, is reduced to the minimum, thus economiziug in the use ot such refrigerant and conserving the time and energy ot the operator.

In the present disclosure I have illustrated and described the protective collar 15 having a gasket 1G which in conjunction with the annular cover 1S and associated thinible 19 constitute the closure for the refrigerant 12, but, it will be obvious and apparent that such protective collar 15 may be dispensed with, it' desired, and the lower end of the thimble 19 provided with the gasket 1G, to seat upon the annular bead 14 of the can 13, thus simplifying and reducing the manufacturing cost oi' the ice cream cabinet herein disclosed.

In practical use and operation the annular space formed by the tub G and ice drum 10 is vfilled with the desired refrigerant 12, a can 13 containing the ice cream or other refrigerated product is then disposed within said ice drum and the protective collar 15 positioned thereon, the annular cover 18 is next positioned to enclose and protect the refrigerant12 after which the cover 22 is placed upon the annular cover '18. Access is obtained to the can 13A by removing the covers 22 and 20, as is obvious.

`While I have herein shownand described v my invention with sufficient detail to enable those skilled in the art to understand the mode of construction and the principles involved, it is to be understood that there is no intentional limitation herein to the specific form and precise details ot construction of the invention shown and described except as expressly defined by the appended claims, and that various modifications of said construction may be resorted to without departing from the invention, or the benets derivable therefrom..
